N/A - Coming from a Notebook

I'm a graphic designer and a photographer as well as a pretty heavy gamer. I need a computer than can balance my gaming and my design - I will be running Windows 7 64-Bit. I can spend up to US$1400, but it'd have to be something that'll sustain itself for a few years. My idea is to get something with a strong enough video card now that'll carry me through the next few years. I'm a complete idiot when it comes to building a PC, so I apologize. I've been browsing the forums and have been getting ideas, but hopefully I can get some more specific feedback.

The thread you linked has some good builds, I would spend a little more on a Gigabyte or ASUS motherboard and buy something like a 6950 or 6970 if you aren't going to wait for the new GPUs in January. A 2500k/compatible motherboard/RAM is the only good base for a build right now.

Recommended for:
Very strong gaming build that will take care
of most gaming needs. Will handle most newer
titles at max or close to max settings given
a resolution of 1080p.

*Mind that the HDD is a bit more expensive.

You'd have to add a desirable keyboard and mouse (if needed) as well as a decent monitor but you should end up within your desired budget. If you need a Windows license, it will most likely end up as a bit too expensive with a 580; in that case, drop down to a Radeon 6970 or a GTX 570.

If the Graphical designs are very CPU heavy I'd probably point you towards the 1000 Workstation build but swap out the GPU for a 560 Ti/6950 (or even a 6970/570 if your budget allows). You would need to swap PSU as well for something with more effect.
